[tex]\tt{\huge{\blue{Explanation:}}}[/tex]
The kinetic energy of a moving object is given by
[tex]\boxed{KE = \frac{1}{2}mv^{2}}[/tex]
where:
KE = kinetic energy
m = mass
v = speed
[tex]\tt{\huge{\red{Solution:}}}[/tex]
Solving for the kinetic energy
[tex]KE = \dfrac{1}{2}mv^{2}[/tex]
[tex]KE = \dfrac{1}{2}(\text{98 kg})(\text{15 m/s})^{2}[/tex]
[tex]\boxed{KE = \text{11,025 J}}[/tex]
Therefore, the kinetic energy of the roller coaster car is 11,025 J.
